Koldioxidhänsligt säkerhetssystem

摘要

One or more sensors or sensor units (1-3) are used to continuously monitor carbon dioxide levels and signals from the sensors are sent to a processor (13) which can transmit an emergency alarm signal if a pre-determined carbon dioxide level is exceeded in any room (A-C). At least one integrated circuit (14) is used to determine an environment-releated value over a pre-selected time period and set off an alarm via an additional circuit (15) if this value exceeds a pre-selected limit.
